Ultrasonic-assisted progressive forming device and process of aluminum alloy ribbed thin-walled components

Abstract

The invention discloses an ultrasonic-assisted progressive forming device and process for an aluminum alloy ribbed thin-walled member. The device includes a box body and a progressive forming device installed inside the box body. The abrasive suspension storage tank below, the general support on both sides of the workbench, the clamping device installed on the workbench, the ultrasonic-assisted forming device and the spraying device located directly above the workbench. Based on the progressive forming device, the thin-walled plate with ribs is progressively deformed layer by layer by using small ultrasonic vibrations, which reduces the difficulty of forming, improves the deformation ability of the material, and further changes the internal grain structure of the material, improving the belt thickness. The surface quality of the ribbed sheet and the strength of the workpiece. The invention can realize three-dimensional movement during processing, improve processing details, and complete precise deformation. The present invention is also provided with a set of suspension circulation system to realize the recycling of the suspension and achieve the purpose of saving the suspension.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an ultrasonic-assisted incremental forming device and a process for an aluminum alloy ribbed thin-walled component. Background technique [0002] Ribbed thin-walled panels are components widely used in aerospace and other high-precision fields. They are not only frequently used in the composition of aircraft shells, but also widely used in the main load-bearing parts of aircraft such as wings and even in space stations. The rigidity and strength can also greatly reduce the structural mass. Therefore, the manufacturing and deformation processing technology of ribbed thin-walled plates occupies an important position in the field of lightweight and high-strength metal manufacturing, and the importance of its development and innovation is self-evident. Because of its high quality requirements, it is usually made of aluminum alloys, magnesium alloys, and titanium alloys with high s...

Problems solved by technology

However, this method is used for extrusion molding. If it is used in single-point incremental molding, there will be a height difference between the filler and the ribs due to the difference in material, which will lead to inability to process, and the strength of the longitudinal ribs will be high, resulting in the molding force. Disadvantages such as uneven application at each point of the component
